Description
Summary:Diesel-driven generator sets (DGs) are widely utilized in distributed electrical power generation due to their high reliability. This paper presents a tenth-order nonlinear state-space DG model, for which a supervisory linear quadratic regulator is designed. The proposed model-based design reduces the time-consuming task of regulator tuning in comparison with current industry-standard solutions while demonstrating improved transient frequency and voltage performance, when subject to electrical load steps. These improvements are shown experimentally on two differently rated DGs.
